CONDUCTOR HOLDER.

. f nc'ation flied March 2, 1921.

Tovau-wh'ma it (10mm Be-it known that we, :JoHN A. Hess and Warm Nnss, citizens oi the United States, and residents of Montevideo, in the county of Chippewa and State of Minnesota, have invented -'certain new and useful Improvein Conduct-or Holders, of which the following is a specification.

This invention relates to an improved line support and insulator for telegraph and telephone line wires, a'nd the like, the device alsofem b'odying an improved holder for the insulator, and the object of the invention being to {proventtho breaking of the telehone or telegraph wires in several places at the :sa'met'ime, in addition to facilitating the hanging "of the wires and permitting the same to be quickly attached or strung and detached from the-supports.

A further object of the invention is to provide {an improved line wire support and insulator which will sufficiently yield to the tension-on the linewires, so as to prevent the same from breaking, while also providinga device which may be readily applied, which 'will'faei l'itate the stringing of wires and the detachment thereof, as well as providing device which may be very economically produced and which is strong and durable. I

Other I and further objects ofour invention will become readily apparent to persons skilled in the artffro'm a consideration of the following description, when taken in conjunction with the accompanying drawings, wherein Eigurel is asectio'n'al view of a cross arm or ib'ar on a telegraph 'p'ole'or the like, provided with the improved line wire support and insulator, and

Figure 2 is amar-"elevation thereof.

Referring to the drawings in detail, in which like reference characters designate corresponding parts throughout the several viewsfthe numeral 10 designates the cross arm or barusually-arranged on telegraph or telephone poles, through which is engaged a bolt 11 suitably secured at the bottom by a nut or the like 12 and having a flange or enlargement 13 engaging the top of the bar or arm. The upper portion 14 of the bolt serves as a support for a wooden or like insulator 15 which is spirally grooved at a point near the bottom continuously to the upper end thereof, as indicated at 16. The wire holder and insulator is designated at I loop Serial No. 448,989.

17 and comprises upper and lower sections having tapered end portions 18 at the top and bottom of the holder and insulator. The lower end of the top section fits within the upper end of the lower section, as inclicated at 19, the lower section being recessed diametrically as indicated at 20, for receiving the line wire 21, which is engaged by a depending portion 22 of the upper section in order to secure and clamp the wire in position.

In order to support the holder 17 upon the insulator 15 a resilient wire is employed which is bent upon itself and one end portion made in the form of a coil 23, the convolutions of which are disposed in the spiral groove of the lower end portion of the insulating element 15. The free end of this coil is extended from the insulating element 15 as at 2 1. The other end portion of the wire is also made in the form of a coil 23 which is disposed in the spiral groove of the insulator 15 and positioned above the coil 23. The lower end terminal of this coil is extended from the insulator 15 as at 29 in a similar manner. The tree upper end of the coil 23 is extended upwardly as at 25 and then outwardly and inwardly to form a loop 26. The upper end portion of the coil 23 is formed with a similar loop 26, and the inwardly extending portions 27 of each of the loops 26 are connected to each other as at 28. This connection may be made by twisting the wires together, as shown, and then the wires are extended apart from each other and again twisted as at 31-and thereby providing a loop 30 adapted to receive the lower section of the holder 17. From the twisted position 3] the wires are brought together and extended upwardly to form a Hinged to the loops or eyes 26 is a clamping loop or ring 33 having its side intertwisted as shown at 3 1 corresponding to the intertwisted portions 28, the loops or rings 30 and 33 serving to securely hold the sections of the insulator 17 in position for movement toward and away from each other. To allow this pivotal movement the extremities of the loop or ring 33 are extended outwardly beyond the intertwisted portion 34, as indicated at 35, and then downwardly at right angles to form parallel portions 36 terminating in eyes 37 which pivotally engage the loops 26. The free end of the loop 33 is arranged to straddle the eye 32 and carries at its end portion or loop 38, a pivotal hook adapted to be engaged with the eye 32 in order to secure the clamping loop 83 in a horizontal position parallel to the loop or ring when the wire 21 is held'in position. Obviously, the hook 39 maybe disengaged from the eye 32 in order to permit the sections to be separated one from the other by raising the loop 33 on its pivot formed by the cooperative loops 2G and the eyes 37, while the hook serves as a locking device for securing the wire in position and the sections of the insulator and holder 17 together. By reason of the vertically extended portions of the coil and the coil itself, the ii'isulator and holder 17 may swing laterally, the wire serving to give sufficiently to prevent tension or drawing on the line wires from breaking the same and especially in several places at the same time, as at present occurs where the wire is rigidly attached to an insulator which cannot give under stress and strain. Also, itwill be apparent that the sections of the insulator or holder 17 may be readily detached so as to permit stringing of the wires with facility, permitting them to be quickly attached and detached. The pivotal connection of the loop forms a hinge by which the upper portion of the insulator 17 may be raised when attaching or detaching the wire 21, while the coil member is held firmly in place and cannot be removed without pressure on the ends 24 and 29, thus rendering said coil self locking. 7

In view of the foregoing, it is thought that the use and operation of the device will be readily understood and in view of the simplicity and practical value, that it will readily commend itself to those skilled in the art.

Having thus described our invention, what we claim is V 1. In a line wire support and insulator, the combination with a spirally grooved insulator suitably supported; of a coiled clamping member engaged on said grooved insulator and tensionally held in the grooves thereof, said clamping member having upwardly directed portions formed with loops extending laterally and a horizontal ring terminating in an upwardly directed portion, and a second ring pivoted to said loops and cooperating with the first named ring to support a sectional insulator therein.

tion, a second ring havinglaterally directed portions pivoted; to said loops for'vertical swinging movement.- a loaning device at the free end of the second named ring to engage,

said upwardly directed portion wherebyto lock the rin in clam in relation for securing and holding a therein.

3. In a line wire support andinsulator, the combination with a spirally grooved in= sulator suitably supported; of, a coiled sectional insulator clamping member engaged on said grooved. insulator and tensionall'y held in the grooves;

tion, a second ring having laterally directed 7 portions pivoted to said'loops for vertical swinging movement, a locking device atthe free end of the second named ring to engage said upwardly directed portion whereby to lock the ring in clamping relation, and an insulator and holder comprising sections carried by said rings and having'cooperative faces to receive and hold a line wire therebetween, said second named ring being adapted to be raised for separating said sections in applying or removing the line, wire.

4. In combination, an insulator, a wire doubled upon itself and having its end-portions wrapped about the insulator and its intermediate portion formed with a loop, a line holder comprising two sections, one of said sections being clamped in the loop', and a second loop of wire pivotally secured ad jacent to said first named loop at its one end for holding the other section of said wire holder, said pivoted loop being adapted'to be connected with the first named loop for locking the two sections of the wire holder together.
